Status messages during draw causes OpenGL error

Description

Event processing during status message display appears to change the OpenGL context to the Qt context. So if this happens during a ChimeraX render it causes an OpenGL error when ChimeraX tries to continue the render after the status message. Ticket #575 was one case of this where solid style volume rendering emitted status messages as it loaded the textures. I fixed that case by removing that status message.

Probably our status message code should check the current OpenGL context and restore it after event processing.

Added OpenGL context caching.

Then I replaced the status line to use OpenGL rendering which also caches the current context.
